Subject: trim support on 2.6.37
Date: Fri, 07 Jan 2011 23:52:18 +0100 [thread overview]
Message-ID: <1294440738.15738.12.camel@jaschtschik-pc> (raw)
Hi list,
It is the first time the i write to this list.
I am not sure if it the right place.
I use the kernel 2.6.37 with cryptsetup and lvm on a intel ssd.
In the logfile after booting i see this entry:
EXT4-fs (dm-1): re-mounted. Opts: discard,errors=remount-ro
EXT4-fs (sda1): mounted filesystem with ordered data mode. Opts: discard
EXT4-fs (dm-3): mounted filesystem with ordered data mode. Opts: discard
EXT4-fs (dm-2): mounted filesystem with ordered data mode. Opts: discard
EXT4-fs warning (device dm-1): ext4_issue_discard:2619: discard not
supported, disabling
EXT4-fs warning (device dm-3): ext4_issue_discard:2619: discard not
supported, disabling
EXT4-fs warning (device dm-3): ext4_issue_discard:2619: discard not
supported, disabling
EXT4-fs warning (device dm-3): ext4_issue_discard:2619: discard not
supported, disabling
EXT4-fs (sda1): re-mounted. Opts: discard,commit=0
EXT4-fs (dm-3): re-mounted. Opts: discard,commit=0
EXT4-fs (dm-2): re-mounted. Opts: discard,commit=0
The mount command shows:
/dev/mapper/System2-root_ssd on / type ext2
(rw,noatime,errors=remount-ro,barrier=1,stripe=32,data=ordered,discard)
and the corresponding entry from fstab:
UUID="635a1ad9-9ebb-4d1e-b8c3-30e11148bd92" / ext4
noatime,discard,errors=remount-ro 0 1
My question is now, I don't have trim support now?
Viele Grüsse
Jens Kasten
